TECHNICAL FIELD

Various embodiments described herein relate generally to networkeddevices and, more particularly, to improved devices, systems, andmethods of enhanced service delivery among the networked devices.

BACKGROUND INFORMATION

Information technology has evolved from a highly centralized andprovider-driven model towards a more decentralized model, which promotesuser empowerment, innovation, and personalization. Thetelecommunications industry makes use of a very hierarchical model ofdevice networking, which governs positioning and roles for the entiresystem, roughly the analogue of centralized mainframe computing beforethe advent of the microcomputer. In such a system, end users operatingat the bottom of this network hierarchy have little or no influence orcontrol on how services they require are delivered to them, and much ofthe computational resources of idle end-users systems, such as CPU(central processor unit) cycles, network capacity, and memory storage,go unused.

DETAILED DESCRIPTION

In the following detailed description of embodiments of the subjectmatter, reference is made to the accompanying drawings, which form apart hereof, and in which is shown by way of illustration specificpreferred embodiments in which the subject matter may be practiced.These embodiments are described in sufficient detail to enable thoseskilled in the art to practice the subject matter, and it is to beunderstood that other embodiments may be utilized and that structural,mechanical, compositional, electrical, and procedural changes may bemade without departing from the spirit and scope of the subject matter.The following detailed description is, therefore, not to be taken in alimiting sense, and the scope of the subject matter is defined only bythe appended claims.

As used herein, the phrase “some embodiments” refers to at least someembodiments of the subject matter. The various appearances of “someembodiments” are not necessarily referring to the same embodiments. Ifthe specification states a component, feature, structure, orcharacteristic “may,” “might,” or “could” be included, that particularcomponent, feature, structure, or characteristic is not required to beincluded. Reference in the specification to “an embodiment,” “oneembodiment” or “an example embodiment” means that a particular feature,structure, or characteristic described in connection with the embodimentis included in at least some embodiments, but not necessarily allembodiments, of the inventive subject matter.

Reference will now be made to the drawings. In order to show thestructures of various embodiments most clearly, the drawings includediagrammatic representations of electronic apparatus. Thus, the actualappearance of the fabricated structures may appear different while stillincorporating the essential structures of the illustrated embodiments.Moreover, the drawings show only the structure or representation thatenables an understanding of the illustrated embodiments. Additionalstructure known in the art has not been included to maintain the clarityof the drawings.

Example embodiments of the inventive subject matter provide apparatusand methods for dispatching, managing, and maintaining services usingvirtual machines in a network, such as a wireless mesh. In exampleembodiments, unused or idle network resources may be used to performservice operations in a manner that occurs in the background and that istransparent to users of the affected devices. The service operations maybe performed in a space-distributed and/or time-distributed manner thatmakes efficient use of unused network resources. In an exampleembodiment, a dynamic supply and demand model is implemented, throughmonitoring network resources to see what resources are available, andthrough appropriate utilization of available resources, as may needed byconsumers of network resources anywhere within the network. In exampleembodiments, the network consumers may include individual users ofmobile devices, and they may also include various types of networkservices; however, network consumers are not limited to these.

Network services may be made especially effective when dispatched on anumber of distributed hosts, such as a plurality of mobile devices in awireless mesh network, as an example embodiment. These services mayinclude grid computing, web proxies, content distribution systems,peer-to-peer file-sharing services, distributed file systems, nameservices, directory services, networking monitoring, and networkmeasurement, as well as any other services, including enterpriseservices, that can take advantage of distribution to a greater or lesserdegree.

FIG. 1 is a block diagram of a network 100 of mobile devices accordingto an example embodiment of the inventive subject matter. In anembodiment, a plurality of mobile devices 101-109 may be interconnectedthrough a suitable wireless network technology.

“Suitable”, as used herein, is intended to include havingcharacteristics that are sufficient to produce the desired result(s).Suitability for the intended purpose can be determined by one ofordinary skill in the art using only routine experimentation.

The mobile devices 101-109 may be any devices with computational,network, and storage capabilities. In example embodiments, the mobiledevices 101-109 are transportable by end users or subscribers. Suchmobile devices may include, but are not limited to, laptop computers;handheld computing devices such as ultramobile personal computers andpersonal digital assistants (PDAs); mobile telephones; entertainmentdevices; communication devices; and vehicle-mounted or transportedcomputer-based equipment.

In FIG. 1, network 100 may be a wireless mesh network among the mobiledevices 101-109. The network 100 may communicate with another network112 (which could be a corporate intranet or the Internet) through atleast one access point 110.

A host computer system or server 130 may also be coupled to network 112.Server 130 may comprise a dispatcher and manager of virtual machines(also referred herein as “VM dispatcher”) 132, and a database 136. TheVM dispatcher 132 and database 136 may be arranged in any suitableorganization or hierarchy. In an example embodiment, the VM dispatcher132 and database 136 may be included within the same host. However, thisarrangement is not essential, and other suitable configurations arepossible. More than one server 130 may be provided to support network100.

The mobile devices 101-109 may communicate wirelessly in an exampleembodiment. However, some mobile devices may alternatively or optionallycommunicate via a wireline connection, either to another mobile deviceor to access point 110. Access point 110 may be coupled to network 112wirelessly or by wireline. Likewise, server 130 may be coupled tonetwork 112 via either a wireless or wireline connection.

In network 100, a plurality of mobile devices 101-104, 106, and 107 maycontain a user operating system (OS). For example, mobile device 101 maycomprise a user OS 114, and mobile device 103 may comprise a user OS118. The user operating systems, such as OS 114 and OS 118, may beidentical to or different from each other.

One or more mobile devices, such as mobile devices 101, 103, 105, and106 may contain a service operating system (OS). Many different types ofservices may be provided. In addition to the services mentionedelsewhere herein, such services may include content distributionservices (including visually and/or audibly perceivable media),processing services including distributed processing, storage servicesincluding distributed storage, communication services including networkmonitoring and security monitoring, and so forth. In network 100, mobiledevice 101 may contain a service OS 116, and mobile device 103 maycontain a service OS 120. The service operating systems, such as OS 116and OS 120, may be identical to or different from each other.

Mobile devices 108 and 109, as depicted in FIG. 1, are not currently inservice. They are illustrated as being coupled to access point 110, butthey are currently idle, and any user or service operating system(s)associated with them may not be operating. They may optionally becoupled to other mobile devices 101-107 while they are idle.

The double-pointed lines coupling various mobile devices 101-109 in FIG.1 represent merely one possible manner of interconnection. In an exampleembodiment, each mobile device may generally be coupled to at least oneproximate mobile device, and several mobile devices are shown to becommunicatively coupled to more than one proximate mobile device. Forexample, mobile device 103 is communicatively coupled to mobile devices102, 105, and 107.

FIG. 2 is a high-level block diagram of a software stack 200 in one ofthe mobile devices shown in FIG. 1, according to an example embodimentof the inventive subject matter. Each mobile device 101-109 may comprisea mobile device virtual machine manager (VMM) 240. The VMM 240 maycomprise a virtual machine (VM) dispatch agent 250.

Each mobile device 101-109 may comprise a plurality of virtual machines(VMs). The software stack 200 of FIG. 2 contains a representation ofthree virtual machines 210, 220, and 230. In an example embodiment, VM210 may be executing a user OS; VM 220 may be executing a first serviceOS; and VM 230 may be operating a second service OS.

VM 210 may comprise CPU resources 212 in the form of at least oneprocessor. VM 210 may comprise further storage resources 214 in the formof any suitable memory device(s). VM 210 may additionally comprisecommunication resources 216 such as at least one communications node orinterface, which may be wireless, wireline, or both.

Similarly, VM 220 may comprise CPU resources 222, storage resources 224,and communication resources 226. Likewise, VM 230 may comprise CPUresources 232, storage resources 234, and communication resources 236.The CPU resources 212, 222, and 232 may be of different or identicaltypes. Likewise, the storage resources 214, 224, and 234 may each be ofdifferent or identical types. Further, the communication resources 216,226, and 236 may each be of different or identical types.

In the mobile device software stack 200 shown in FIG. 2, the VM dispatchagent 250 has instantiated a virtual machine (VM) 210 running a useroperating system (OS). The user of the mobile device interacts with VM210 running the user OS, which has been allocated CPU resources 212,storage resources 214, and communication resources 216 by the VMM 240.

Invisible to the user, who optionally may only interact with the userOS, there may be one or more virtual node modules or machines 220 and230 that may run a service OS that is dedicated toward running a serviceof the types mentioned above. The VM dispatch agent 250 may monitorresource consumption and network connectivity, and it may periodicallysend information relating thereto to a remote VM dispatcher, such as VMdispatcher 132 (refer to FIG. 1) on server 130.

FIG. 3 is a flow diagram 300 of example methods that could be carriedout on devices in a network, such as a mobile device 101 and a VMdispatcher 132 in FIG. 1, in accordance with various embodiments of theinventive subject matter. FIG. 3 shows a process for a user of a mobiledevice or for a network service to request one or more virtual machinesin a network, such as a wireless mesh network.

The flow diagram 300 may be started in block 302 and/or 305. Blocks 310,312, 314, and 316 are common to both of the starting branches that beginwith 302 and 305, respectively.

In 302, a network service may send a request to the server's VMdispatcher (e.g. VM dispatcher 132, FIG. 1) for one or more virtualmachines with specific resource requirements.

In 305, a user on a mobile device or system such as a mobile device 101in FIG. 1 may send a request to its associated VM dispatch agent toinstantiate a network service, including service requirements andpointers to virtual machine images. In an embodiment, the user may sendthe request directly. In an alternative embodiment, the user may sendthe request indirectly, such as when a process the user is running onthe mobile device makes the request a part of its normal operation. Inan embodiment, the request for network service may include servicerequirements. In an embodiment, the request for network service mayinclude pointers to virtual images.

In 307, the VM dispatch agent may send the request, including anyservice information, through the mesh network to the server's VMdispatcher (e.g. VM dispatcher 132, FIG. 1). In an alternativeembodiment, the request may be sent directly to the VM dispatcher fromthe user.

In 310, the VM dispatcher may look at a record or database of availableresources to identify a resource that will satisfy the request, and itmay send a VM request for those resources to the VM dispatch agent(s)associated with one or more mobile devices that can provide suitableresource(s). In an embodiment, the VM dispatch request(s) may be sentonly to mobile devices having suitable resources for the virtual machineresource being requested.

In 312, the request for VM creation and VM resources is received by theVM dispatch agent(s), which may talk to the VM dispatcher 132 andrequest that one or more virtual machines for the service be created.This method enables mobile device resources to be utilized for theprovision of a service.

In 314, the VM dispatcher may command the VM dispatch agents to eachcreate a VM. In an embodiment, the virtual machines to be created mayinclude virtual machines to perform network services, such as thosementioned elsewhere herein.

In an embodiment, the virtual machines to be created may include virtualmachines to perform storage services, such as a distributed hash tableservice, or any storage services of the types mentioned elsewhereherein.

In an embodiment, the virtual machines to be created may include virtualmachines to perform computing (CPU) services, such as providing CPUcycles to run simulations, or any computing services of the typesmentioned elsewhere herein.

In 316, the requesting user or network service uses the newly createdone or more virtual machines to perform one or more desired functions orto provide one or more desired services. In an embodiment, the newlycreated virtual machines may include any combination of the virtualmachines described in 314. In another embodiment, the newly createdvirtual machines may include other resources such as network and/orstorage resources.

An example of a network service requesting VM resources in the meshnetwork will now be discussed. As mentioned earlier, the users of mobiledevices 101-104, 106, and 107 “see” only a user OS (e.g. user OS 210,FIG. 2) in their interactions with mobile devices 101-104, 106, and 107,respectively. Let us assume that a content distribution service (merelyas an example) desires to distribute files to all of the mobile devices101-109. Distributing the files from network 112 may lead to a potentialbottleneck at access point 110 as well as at the nodes (not shown)inside network 112 that might distribute the files.

In example embodiments of the inventive subject matter, the contentdistribution service may utilize the computational, storage, and networkresources of mobile devices 101-109 to provide the service. When theservice needs to use resources in mesh network 100, it may send arequest to the VM dispatcher 132 for such resources. VM dispatcher 132looks in its database 136 of available resources, finds that mobiledevices 101, 103, and 106, for example, have sufficient resourcecapacity to distribute, store, and process the files, as requested, andit then sends a message to the VM dispatch agents on mobile devices 101,103, and 106. The message may request that a service OS VM be created(e.g. Service OS #1, also identified as Service OS 220). As a result,service OS VM 220 is created on those mobile devices 101, 103, and 106,enabling other mobile devices close to them to get the distributed filesfrom mobile devices 101, 103, and/or 106 without having to access thecontent distribution service through access point 110 and network 112,thus reducing the network traffic through access point 110 and onnetwork 112.

FIG. 4 is a flow diagram 400 of example methods that could be carriedout on devices in a network, such as a mobile device 101 and a server130 in FIG. 1, in accordance with various embodiments of the inventivesubject matter.

In 402, a VM dispatch agent on each mobile device monitors for changesin computational resources, storage resources, and/or communicationsresources. The VM dispatch agent also checks for dynamic changes to thenetwork resources, such as mobile devices that may have dropped out ofor left the network or that may have recently entered the network, e.g.through physical movement into the network and/or through activationwithin the network.

In 403, a determination is made by a suitable determination unit orelement whether a change in resources in the mesh network connectivity,in CPU utilization, or in memory storage has occurred. If so, in 404,the determination element sends a message to the VM dispatcher to notifyor inform it that a change in resources has occurred. In an embodiment,the VM dispatch agent may detect an actual change in resources in themesh network. In an alternative embodiment, the VM dispatch agent maypredict a change in resources in the mesh network based on an analysisof suitable factors.

In an embodiment, a change in the mesh network connectivity may becaused by an event such as a mobile device entering or leaving the meshnetwork, by a change in signal propagation between mobile devices on themesh network, by a change in user load on the mesh network, or the like.In an embodiment, a change in CPU utilization may be caused by an eventsuch as a mobile device entering or leaving the mesh network, by amobile device entering or leaving standby mode, by a mobile deviceperforming CPU intensive operations, and so on. In an embodiment, achange in storage may occur when a mobile device saves or deletes datafrom its local storage device, or when local storage capacity is addedto or removed from a mobile device.

In 405, the VM dispatcher updates its resource database and maydetermine whether any running services are affected, using a suitabledetermination unit or element. In an embodiment, running services thatmay be affected include, but are not limited to, content distribution,network measurement, and grid computation.

In 406, a suitable determination element (not shown) associated with theVM dispatcher may check to see whether the change in resources affectsany running services. If no running services are affected by the changein resources, the method ends. If any running services are affected bythe change in resources, then the method may continue to 407. In anembodiment, the method may be structured as a loop. In such anembodiment, when the method ends, it may begin again from the beginningeither immediately, or after a delay. In an alternative embodiment, themethod does not begin until it is triggered by a suitable event.

In 407, the VM dispatcher may allocate other resources within the meshnetwork and send a dispatch message to create or migrate virtualmachines accordingly. In an embodiment, virtual machines may be createdafter a new mobile device has been detected on the mesh network. In anembodiment, virtual machines may be created in response to additionalstorage capacity being detected on the mesh network. In an embodiment,virtual machines may be created in response to a change in networkconnectivity within the mesh network. In an embodiment, virtual machinesmay be migrated from a mobile device leaving the mesh network to amobile device remaining on the mesh network. In an embodiment, virtualmachines may be migrated from a mobile device with a high number ofrunning processes to a mobile device with a lower number of runningprocesses. In an embodiment, virtual machines may be migrated from amobile device with a small amount of available storage capacity to amobile device with a larger amount of available storage capacity.

In an embodiment, other resources may be allocated, and appropriatevirtual machine migration or creation messages may be sent to theappropriate mobile devices. In such an embodiment, the VM dispatcher mayadapt to changing conditions in the mesh network.

FIG. 5 is a flow diagram 500 of example methods that could be carriedout on a mobile device and a virtual machine dispatch host, such as amobile device 101 and a VM dispatcher 132 in FIG. 1, according tovarious embodiments of the inventive subject matter.

In 502, a hardware and/or software problem on a mobile system such asmobile device 101 in FIG. 1 is reported to the VM dispatcher 132, eitherfrom a monitor system or via a help request from the user of the mobiledevice. In an embodiment, the problem may be reported automatically. Inan alternative embodiment, the user may choose whether the problem is tobe reported, or the user may manually report the problem. A suitablemonitor system may, for example, be dedicated to detecting operationalhardware and/or software errors in a mobile device.

In 503, the VM dispatcher 132 sends a request to the VM dispatch agentassociated with the mobile device 101 experiencing the problem. Therequest instructs the VM dispatch agent on the mobile device 101 tomigrate the user OS 114 to a spare unused mobile device, such as mobiledevice 108. In an embodiment, the spare unused mobile device or systemmay be one that the user currently owns. In an alternative embodiment,the spare unused mobile device may be supplied to the user by a sourceof idle mobile devices. An organization's IT (Information Technology)department may keep spare unused mobile devices and systems as part of apool of spare equipment.

In 504, the VM dispatch agent on the mobile device 101 may migrate theuser OS 114 to an idle mobile device 108, where it is restarted. In anembodiment, the user OS 114 may be shut down on the mobile device 101experiencing problems before being migrated. In an alternativeembodiment, user OS 114 may be migrated to an idle mobile device 108 andnot restarted on the original mobile device 101.

FIG. 6 is a flow diagram 600 of example methods that could be carriedout on mobile devices in a network, such as a mobile device 103 and a VMdispatcher 132 in FIG. 1, according to various embodiments of theinventive subject matter.

In 602, a user on a mobile device, such as mobile device 103 in FIG. 1,may send a request to its associated VM dispatch agent to changeresource requirements for a network service. In an embodiment, the usermay send the request directly. In an alternative embodiment, the usermay send the request indirectly, such as when a process the user isrunning on the mobile device makes the request as part of its normaloperation. In an embodiment, the request to change resource requirementsfor a network service may be made in response to a change in networkactivity such as traffic, bandwidth usage, CPU usage, storageavailability, or the like.

In 603, the VM dispatch agent 235 may send the request and serviceinformation to the VM dispatcher 132 on the server 130 (refer to FIG.1). In an embodiment, the VM dispatch agent may forward the request,including any service information, through the mesh network 100 to theVM dispatcher 132. In an alternative embodiment, the request may be sentdirectly to the VM dispatcher 132.

In 604, the VM dispatcher 132 looks at its record or database 136 ofavailable resources and may send virtual machine creation or migrationrequests to mobile devices, as needed, to meet the requirement change.In an embodiment, the number of virtual machine creation or migrationrequests sent may vary depending upon the number of physical hosts ormobile devices available. In an embodiment, the number of virtualmachine creation or migration requests sent may vary depending upon theresources available on the available physical hosts or mobile devices.

In 605, the virtual machine dispatch agents on the physical hosts ormobile devices may talk to the VM dispatcher and request that virtualmachines for the services be created, destroyed, or migrated, as may besuitable. In an embodiment, the virtual machines to be created,destroyed, or migrated may include virtual machines to perform networkservices such as those mentioned above. In an embodiment, the virtualmachines to be created, destroyed, or migrated may include virtualmachines to perform storage services such as those mentioned above. Inan embodiment, the virtual machines to be created, destroyed, ormigrated may include virtual machines to perform computing (CPU)services such as those mentioned above.

In 606, the network service may use the adjusted virtual machines toprovide service at the updated requirements.

FIG. 7 is a flow diagram 700 of example methods that could be carriedout on devices in a network, such as a mobile device 101 and a VMdispatcher 132 in FIG. 1, in accordance with various embodiments of theinventive subject matter.

In 702, a hardware and/or software problem with the user OS on a mobiledevice such as mobile device 101 in FIG. 1, may be reported either froma monitor system or from a help request from the user of the user OS 114on the mobile device. It is assumed for this particular example that theproblem requires a restart of that user OS 114. In an embodiment, therestart may require stopping all processes and services running on themobile device. In an embodiment, the restart may require stopping onlysome processes or services running on the mobile device. In analternative embodiment, the restart may require only that the user logout and log in again.

In 703, the VM dispatcher 132 may send a request to the VM dispatchagent on mobile device 101 for the rebooting of the user OS 114. In anembodiment, the reboot request may be initiated directly by a user ofthe user OS 114 on the mobile device 101. In an embodiment, the rebootrequest may be generated automatically by a user OS monitoring system(not shown).

In 704, the VM dispatch agent on the mobile device 101 may reboot theuser OS 114.
